Multilevel graphs serve to represent networks with different ``levels'' such as different domains in the network structure. A characteristic of multilevel networks is the existence of ties within and across domains.
Since this function can handle a large number of arguments, these can be stored as a list object that is passed through the scope option.
In this case, a vector made of lists and scalars or combinations of these is accepted.
The bundle width specified by bwd and bwd2 ranges from 0 (edges collapsed) to the default 1 (depending on the vertices' size).
For the valued option, a number greater than one is possible.
In a multilevel structure, argument clu is to class network members
and it is possible to class all members of the domain or co-domain into a single class by setting the vector to NULL.
Similarly, NULL in argument nr for the conc layout implies the use of two radii, one for each domain.
